Applied for J-1 Waiver can I travel back to India for few days

[Kanya Maji]

Hi I am here in USA on J1 visa status, recently I have applied for Waiver and I am on stage 2. Can I travel back to India for few days as some emergencies came in my home. My passport visa is expired but I have a valid DS2019 so if I go I have to apply for J1 visa again .

Can I travel or if I travel my Waiver process still consider as valid or not please reply .
thanks in advance
